Learning outcomes Provide the knowledge and application of fundamental principles of contact lenses fitting as an alternative method to the most traditional processes of compensation of ametropia.

Thereby, the student should be able to:
- Identify the physiological changes and ocular pathologies induced by contact lens wear.
- Plan and select the contact lens that best suits a potential user based on preliminary tests and routine.
- Apply the procedures necessary for contact lenses fitting.
- Analyze and describe a contact lens fitting based on their behavior.
- Provide and apply solutions in order to improvement the adaptation of contact lenses.
- Select the most appropriate maintenance system according to the type and utilization schema of contact lenses.
- Plan and apply the several control and review procedures for contact lenses.
- Discuss possible alternatives to the use of contact lenses.
Syllabus Theoretical classes:
1. Contact lens materials.
2. Contact lenses geometry.
3. Contact lens optics.
4. Ocular infections and immune defenses.
5. Physiological changes in ocular structures by the use of contact lenses.
6. Corneal pathologies induced by contact lens wear.
7. Deposits and cleaning solutions for contact lenses.
8. Preliminary procedures for fitting contact lenses.
9. Fitting rigid gas permeable contact lenses with spherical and aspherical geometry.
10. Fitting hydrophilic contact lenses with spherical and aspherical geometry.
11. Fitting hydrophilic contact lenses with toric geometry.
12. Procedures for review and control of contact lenses.

Practical classes (skills):
1. Biomicroscopy.
2. Preliminary and routine exams in contactology.

Planned learning activities and teaching methods The UC comprises theoretical-practical and laboratory classes. The theoretical-practical classes are organized by combining two teaching methods: - Exposure classes (supported by slides) and presentation and discussion of scientific papers by the students. Parallel is provided a set of questions for self-study, which are object of discussion during the theoretical-practical sessions. The laboratory classes are structured in two phases: - the first dedicated to a small briefing for consolidation practical contents, and the second for development practical skills by carrying out practical procedures inherent to the selection, adaptation and decision on potential users of contact lenses.
Metodologias de Ensino e Critérios de Avaliação A avaliação de conhecimentos integra duas componentes: Avaliação teórico-prática que integra 1 prova escrita, e avaliação prática laboratorial que contempla a resolução de casos práticos de contactologia.
Language Portuguese. Tutorial support is available in English.
